Heterodimeric proteins

Abstract

In one aspect, the present invention provides heterodimeric antibodies comprising a first monomer comprising a first heavy chain constant domain comprising a first variant Fc domain and a first antigen binding domain and a second monomer comprising a second heavy chain constant domain comprising a second variant Fc domain and a second antigen binding domain. In an additional aspect the heterodimeric antibody comprises a first monomer comprising a heavy chain comprising a first Fc domain and a single chain Fv region (scFv) that binds a first antigen, wherein the scFv comprises a charged scFv linker. The heterodimeric antibody further comprises a second monomer comprising a first heavy chain comprising a second Fc domain and a first variable heavy chain and a first light chain.
